“So, having spent the last couple of years experimenting with UAV systems I felt the need to try something that would stay on the ground. I have been fascinated by rock crawlers, the latest RC off-road trend. They seem the be the ideal platform for a land based all terrain rover system. Traction and maneuverability is very impressive.”

“I’ve had this one TAC-2 controller lying around with a broken cord and one day I just got an idea that maybe I’ll convert it to wireless version instead of fixing the cord so I could use it for controlling a robot or whatever comes in my mind. I ordered a set of modules for a 433 MHz RF link from SparkFun Electronics (transmitter and receiver) that are easy to use.”

“After seeing circuit details I discovered it used some pic18F2550 as was almost compatible with dangerousprotypes IR Infrared Toy, so I downloaded firmware and programmed succesfully this device easily without modifiying firmware source code.”

“This is my favourite project, its too simple and very interesting because it does not require any voltage source 😀 it converts RF frequency waves from cell phone (whenever you call or send a text) to little current to flash a LED.”

“In this tutorial we will see how to make simple infrared sensor module for detecting reflecting surface. This sensor can be used to detect reflecting silver/white strip, obstacle detection, flame detection, etc. These sensors are primary requirement of any simple line follower robo-car.”

“About one month ago I had a request to write about break-beam sensors. So, here it is! Well, basically break beam sensor consists of two parts: transmitter and receiver. Transmitter emits light and that light goes to receiver. If that light beam between transmitter and receiver is broken by some obstacle, and receiver detects no incoming light even for a brief moment – it triggers an alarm.”

“Although we have been having fun making things on our desks or work benches, it is time to slowly enter the real world and hack something up. The other day I was in a variety store to buy some glue, and happened across a very cheap remote-control car. After noticing it had full directional control (left, right, forwards and backwards) it occured to me that we could control it with an arduino.”

“Our gesture input system can be conveniently used by anyone who wishes not to be tied down to a desk when using a computer, making it perfect for giving presentations or web surfing from the couch. The intuitive hand motion controls also allow it to serve as an alternative video game controller.”

“I have for a long time wanted to build a remote controllable balancing robot aka Segway – that was actually the main reason why I created the PS3 Bluetooth Library both for Arduino and the FEZ Devices….I decided to step up a notch and go for a much more powerful device: the mbed microcontroller, which is an ARM Cortex-M3 running 96MHz…The robot also features an Arduino Duemilanove with a USB Host Shield on top running a sketch based on my PS3 Bluetooth Library.”

“Standard DC motor control can be tricky enough if you are new to electronics, but how about wireless dual dc motor control? A while ago I introduced you to a simple dual dc motor control design that used the SN754410NE IC to control some off-the-shelf 3v or 6v motors. Let’s take a look beyond just motor control and see if we can’t make that same system wirelessly controlled.”
